Description

Technical Field

[0001] This utility model relates to the field of cue tip repair, and in particular to a cue tip side repair device. Background Technology

[0002] Tip trimming primarily refers to the process of adjusting the side profile of the cue tip. There are two common situations requiring trimming: First, after a period of use, the edges of the cue tip gradually wear down, becoming uneven or developing burrs, affecting shot stability. Second, when installing a new cue tip, its edges are usually close to a 90-degree right angle or have a slight chamfer, making it too square and requiring trimming; otherwise, it may easily scratch the cue ball's surface and cause damage. Tip trimming helps maintain the optimal curvature of the cue tip, ensuring stable contact area and friction with the cue ball during shot, thus improving shot stability. While existing tip trimming tools have this function, they suffer from limitations such as limited applicability to certain sizes and the potential for damaging the apex. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a cue tip trimmer that can accurately trim tips of various sizes and effectively protect the tip of the cue from damage.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A billiard cue tip trimmer includes a connecting sleeve with a threaded, equal-diameter section and a tapered, variable-diameter section. A locking sleeve is connected to the lower end of the connecting sleeve. The top of the locking sleeve has multiple claws that mate with the equal-diameter and variable-diameter sections, allowing adjustment of the locking inner diameter formed by the claws by rotating the locking sleeve. A trimmer head is connected to the upper end of the connecting sleeve. A trimmer hole is formed in the lower part of the trimmer head. A limiting rod extending into the trimmer hole is threaded to the top of the trimmer head. A trimmer opening is provided on the side of the trimmer head corresponding to the trimmer hole, and a trimmer blade is installed at the trimmer opening. The trimmer head is slidably connected to the top of the connecting sleeve along the radial direction of the locking inner diameter, with the sliding direction of the trimmer head facing the trimmer opening, allowing the trimmer head to slide relative to the connecting sleeve to adjust the trimming depth.

[0006] Furthermore, along the sliding direction of the side trimming head, lateral concave grooves are respectively provided on both sides of the connecting sleeve, and lateral protrusions that cooperate with the lateral concave grooves are respectively provided on both sides of the bottom of the side trimming head to provide vertical positioning during the sliding process of the side trimming head.

[0007] A limiting groove is formed on one side of the top of the connecting sleeve along the sliding direction. A vertical stepped hole is formed on the side trimmer head corresponding to the limiting groove. A countersunk bolt is connected in the vertical stepped hole. The lower end of the countersunk bolt extends into the limiting groove to limit the sliding range of the side trimmer head.

[0008] Furthermore, the top of the limiting rod is provided with an operating part, specifically an operating slot is provided thereon.

[0009] The advantages of this utility model, which adopts the above-mentioned technical solution, are as follows: The billiard cue tip side-repairing device, through the adjustment of the limiting rod, can prevent the tip from extending to the side-repairing blade position, thus avoiding damage during side-repair; the locking sleeve and connecting sleeve cooperate to initially position the billiard cue, facilitating subsequent stable side-repair; the side-repair depth can be adjusted by the sliding arrangement of the side-repairing head and connecting sleeve to suit different sized tip repairs. This billiard cue tip side-repairing device also has the advantages of simple structure and ease of disassembly and assembly. Attached Figure Description

Detailed Implementation

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-6As shown, in this embodiment, the billiard cue tip trimmer includes a connecting sleeve 1. The connecting sleeve 1 has a threaded equal-diameter section 11 and a tapered variable-diameter section 12. A locking sleeve 2 is connected to the lower end of the connecting sleeve 1. The top of the locking sleeve 2 has multiple claws 21 that mate with the equal-diameter section 11 and the variable-diameter section 12, allowing adjustment of the locking inner diameter formed by the multiple claws by screwing the locking sleeve. A side trimming head 3 is connected to the upper end of the connecting sleeve 1. The lower part of the 3 has a side trimming hole 31. The top of the side trimming head 3 is threadedly connected to a limiting rod 32 that extends into the side trimming hole 31. The side trimming head 3 has a side trimming opening 33 on one side corresponding to the side trimming hole 31. A side trimming knife 34 is installed at the side trimming opening 33. The side trimming head 3 is limited and slidably connected to the top of the connecting sleeve 1 in the radial direction of the locking inner diameter. The sliding direction of the side trimming head 3 is set towards the side trimming opening 33 so that the side trimming head 3 can slide relative to the connecting sleeve 1 to adjust the side trimming depth.

[0019] Side trimming principle: (1) Insert the cue stick from the bottom of the locking sleeve into the side trimming hole of the side trimming head, and then adjust the height of the limit rod to prevent the tip from extending to the side trimming knife position; (2) Twist the locking sleeve to clamp the cue stick through multiple claws, specifically to stabilize the cue stick but allow it to be rotated manually; (3) Slide the side trimming head to adjust the side trimming depth. After adjustment, hold the side trimming head with one hand and keep it stationary relative to the connecting sleeve, and rotate the cue stick with the other hand. The cue stick can be side trimmed by the side trimming knife. Rotate one revolution until the side trimming is completed.

[0020] The above-mentioned cue tip trimmers not only protect the tip from damage, but are also suitable for trimming tips of different sizes. They also provide good uniformity of circumferential trimming, preventing uneven trimming on one side.

[0021] In one embodiment, to facilitate the processing and disassembly of the side trimming head and the connecting sleeve, the following structural configuration is made: Specifically, along the sliding direction of the side trimming head 3, lateral concave grooves 13 are respectively provided on both sides of the connecting sleeve 1, and lateral protrusions 35 that cooperate with the lateral concave grooves 13 are respectively provided on both sides of the bottom of the side trimming head 3 to provide vertical limitation during the sliding of the side trimming head 3; a limiting groove 14 is provided on one side of the top of the connecting sleeve 1 along the sliding direction, and a vertical stepped hole 36 is provided on the side trimming head 3 corresponding to the position of the limiting groove 14. A countersunk bolt 37 is connected in the vertical stepped hole 36, and the lower end of the countersunk bolt 37 extends into the limiting groove 12 to limit the sliding range of the side trimming head 3.

[0022] During installation, first, slide the lateral concave groove 11 and the lateral convex part 35 together. After mating, the side trimming head 3 and the connecting sleeve 1 can only be moved relative to each other in the sliding direction and cannot be removed vertically. Then, install the countersunk bolts and tighten them until their lower ends extend into the limiting groove 12. This restricts the sliding range of the side trimming head 3, preventing it from sliding out of the connecting sleeve while allowing adjustment of the side trimming depth. The above structure is relatively convenient and easy to process, install, and remove. Removal is performed by reversing the above steps.

[0023] In one embodiment, an operating part can be provided at the top of the limiting rod 32 to facilitate the adjustment of the limiting rod by turning it. Specifically, the operating part can be an operating slot opened on the top surface of the limiting part.

[0024] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0025] Any aspects of this utility model not described in detail are known to those skilled in the art.
